You'll need a box, tape, padding material, and your shipping label.

Please Read: Important Information

Please DO NOT send us your one-of-a-kind, irreplaceable mouthpiece. Accidents sometimes happen - and can be irreparable when using cutting machinery. If your mouthpieces is damaged during the modification process we will replace it with a mouthpiece of like model and condition - but a one-of-a-kind or old mouthpiece may be irreplaceable.

With Modify My Piece, you are purchasing the modification service only - not the mouthpiece.

Please make us aware of any previous modifications that have been done to your mouthpiece.

The shipping charges cover shipping your mouthpiece back to you. (It is your responsibility to get your mouthpiece to us - and any shipping charges from you to us).

When will my mouthpiece be shipped back to me? The time estimate at the top when selecting the desired service(s) reflects the time it takes for that modification to be completed after we have received your mouthpiece.

Once we have received your mouthpiece we may deem it to be unfit for some or all modifications. This may be because of wear-and-tear of the mouthpiece or because previous work on the mouthpiece hinder further modifications. If this is the case, we will return your mouthpiece and issue a refund minus the cost of shipping.

Please note: Modification orders are considered Special Order so your Credit Card/PayPal account will be charged immediately - at the time you order.

Mouthpiece Express is not responsible for lost or damaged packages.

By purchasing our modification service you agree to these terms and conditions above.
